PROBLEM TO BE SOLVED: To provide a rotation angle detection device capable of more secure angle detection, even when axial runout occurs in a detection object shaft. SOLUTION: When being used in a system having a small tolerance on the side wherein an output voltage showing a detection result is small, and having a large tolerance on the side wherein the output voltage is large, in this rotation angle detection device, a magnetic neutral position is set so that a fluctuation width of the detection result resulting from runout of a shaft 15 in the direction (C direction) wherein the runout of the shaft 15 which is a detection object shaft becomes maximum becomes larger in proportion to largeness of a detection allowance carried by each rotation angle.
